I just thought I'd let you all know I took a passion of mine and monetized it, and I've been actually making a few sales with it.

They're very simple icosahedral templates really, but the patterns I designed across their faces have some M.C. Escher-like appeal to them, and the potential to create other interesting patterns is there for the buyer of my product.

I don't mean to make this a blatant advertisement for my book; I just thought you all would like to know that you can take your interest in 3D models and do something with it to monetize it. It CAN work.

What about offering other shapes, such as the stella octangula, rhombic dodecahedron and maybe even small stellated dodecahedron?
I have a large-ish model of a small stellated dodecahedron made of shiny golden card that I bring out every Christmas: just print the net on the back.
